Salt superfine grinding mill
Table salt or common salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater, where it is the main mineral constituent. The open ocean has about 35 grams (1.2 oz) of solids per litre, a salinity of 3.5%.
Salt is essential for life in general, and saltiness is one of the basic human tastes. The tissues of animals contain larger quantities of salt than do plant tissues. Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation.
Some of the earliest evidence of salt processing dates to around 8,000 years ago, when people living in an area in what is now known as the country of Romania were boiling spring water to extract the salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, the Greeks, the Romans, the Byzantines, the Hittites, Egyptians, and the Indians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, and across the Sahara in camel caravans. The scarcity and universal need for salt has led nations to go to war over it and use it to raise tax revenues. Salt is used in religious ceremonies and has other cultural significance.
Salt is processed from salt mines, or by the evaporation of seawater (sea salt) or mineral-rich spring water in shallow pools. Its major industrial products are caustic soda and chlorine, and is used in many industrial processes including the manufacture of polyvinyl chloride, plastics, paper pulp and many other products. Of the annual global production of around two hundred million tonnes of salt, only about 6% is used for human consumption. Other uses include water conditioning processes, de-icing highways, and agricultural use. Edible salt is sold in forms such as sea salt and table salt which usually contains an anti-caking agent and may be iodised to prevent iodine deficiency. As well as its use in cooking and at the table, salt is present in many processed foods.
Sodium is an essential nutrient for human health via its role as an electrolyte and osmotic solute. Excessive salt consumption can increase the risk of cardiovascular diseases, such as hypertension, in children and adults. Such health effects of salt have long been studied. Accordingly, numerous world health associations and experts in developed countries recommend reducing consumption of popular salty foods. The World Health Organization recommends that adults should consume less than 2,000 mg of sodium, equivalent to 5 grams of salt per day.
Fengli ACM/A series are highly efficient superfine punch-action mechanical micro grinding machines of performing the complete process of salt grinding, separation and making of the finished product within the same tightly integrated system.
1. Built-in separation mechanism-preventing over-grinding.
2. Able to produce uniform granules of required sizes by adjusting the speed of the stage-separation wheel(s) or by adjusting the strength of the blower(s).
3. Powerful blowing and strong self-cooling capability, suitable for grinding heat-sensitive materials.
4. Different grinding accessories/devices are used according to the hardness of the material being ground; different types of materials (alloyed carbon steel, stainless steel, ceramics etc) are available for the Machine’s inner linings and product extracting system, meeting the needs of different industries.
5. Both manual and programmable auto-controlled machines available.
The machine is suitable for super-fine grinding of various types of brittle materials. Material hardness (Mohs scale)<4, moisture contents<10%, input size 5–200mm (as decided by the model of the machine and material hardness). The machine is widely used coating materials and other industries.
